of the regulator to be actuated simultanea ously therewith, and. i

Fig; 4 is a -fragmentary sectional View particularly illustrating' 'thedetachable mounting Iof the .lever arm .lof the thermostat of theregulator.

In order that the construction, mounting and operation of my improvedregulator' may be 'accurately understood I have, in Fig. 1 of thedrawings, shown-the. device in connection with aconventional.:typeofjin`- cubator 10 provided with an e g chamber Y11and equipped with a lamp ue 12 from the lamp casing 13 of the incubator.In

carrying out the invention` I employ complem'ental lever Stands 14 whichare mount..

#ed upon the top of the incubator in any approved manner. One of thesestandsis shown in detail inv Fig. 2. Mounted upon the said stands arecoacting regulating levers 15and-16 respectivel These levers include Yfulerum members l; and 18 respectively through'which extend rods 19engaged through' ears 20'upon the stands 14 and pivotall'yfconnectingthe said members withthe stands. Asparticularly shown in Fig. 1,theflevers" 15a11d. 16` 'each include a long arm andja* shorterm. Forconvenience, the shorter arms of the said levers have v been indicatedat 21 and 2 2 respectively. Connected to the longer arm ofthe lever 15isy adamper 23 arranged to close a suitable vent iiue from the eggchamber- 11 ofthe-in cubator. The longer arm ofthe lever 16 is equippedwith a 'similar'.l damper 24er-4 ran ed to close the lamp ue 12.` T 'eshorter'larm 21 of th lever 15- is preferably formed from a length of'suitahle resilient-.wire bentv intermediate its e dsl to prcvfde'apivotloop' or connecting'.` m er levereland gs'glecoun. .1^ CerniaVlengin anyapprpved 'manner with the" Stands enga-viera@ hiel. loop..serves-j te4 pivot-',;

l ed upon the stud 33 projecting into the egg chamber 11 and connectedat their 'lower ends by a cross bar 30 t0form a supporting framefourths, thermostat'. Mounted upon the said bar is a thermostat 31)referably formed of coacting wafers. rejecting from one side of thethermostat is a stud threaded through the bar 30 for detachablyconnecting the thermostat with the said bar. jecting from the oppositeSide of .the thermostat is a similar stud Screw threadis a cross head34, which is thus detachably connected with the thermostat. At itsextremities, the cross head 34 is iven a half turn and is provided withsuitabqe openings. Detachably engaging through these openings areconnecting rods 35 which extend within the posts 29 of the supportingframe for the thermostat and project through the fulcruin members 17 ofthe levers '15 and 1G. Screw threaded upon theupper extremities of thesaid rods are adjusting' nuts 3G.

lAs will now be readily understooifl, the thermostat 3l will, of course,expand as the temperature of the egg chamber 11 rises. Expansion of thesaid therin-ostht. will move the cross head 34 downwardly andaccordingly simultaneously pivot the regulating levers i4 and 15 toraise the d ainpers 0 pivotally .i3 and 24;. Since the levers areconnected at their inner ends, the said levers will always move inunison and by adjusting the nuts 36, the temperature at which thedempers 23 and 24 shall be raised, may

' be easily varied.

It. will therefore be seen that I provide a particularly simple, andellicientl construction forv the` purpose. set tort-li. In this` con--nection, particular attention is directed to the facty that should thecross head 3l ot' the thermostat become broken or its elliciencyntheru-'ise 'in'ipaireih the connecting rods 35 inav be disengaged fromthe said cross head when the cross head may be detached by Simplyunscrewing it from the post of the thermostat` This` provides a1convenient arrangement whereby the cross head may be quickly renewed orrepaired.

In Fig'. 3 of the diraAvingsJ ha ve'illustrated the manner in which anauxiliary regulating lever may be employed ais a part of my improvedregulator. ln this [igurc an incubator has been conventionally shown at.37. Mounted upon the top wall of the incubator are the lever stands 1lcarrying the regulating-levers l5 and lo connected at their inner ends`by the pivot. loop 25'. pers 237 and 24 of these levers arerespectivelyarranged to close, a. vent flue 'leading to each of the eggchanibers of tl'ieincubator.
